GLASS-ANNEALING FU RNAQE SPECIFICATION forming part of Letters Patent No. 508,934, dated November 21, 1893. 1

Application filed February 26,1892, fierial No. 422,944. (No model.)

To all whom it concern:

Be it known that we, J APHUsGEoReE and Q CHRISTOPHER MICHAEL SHORTLE, citizens of the United States of America, and residents of Ithaca, Tompkins county, New York,have invented an Improved Glass-Annealing Furnace, of which the following is a specification, reference being had to the accompanying Y compassing circular chamber, and secondly in the relation of theannealing wheel to the flattening wheel, made in the usual manner, over the coolerv portion of which it laps, ex-

tending into the flattening chamber: and our invention relates to several lesser parts,which will be apparent in the following description.

Figure 1 is a view looking down on a section, madetransversely just above the annealing and the flattening wheels; and is a ground plan of both the said wheels and their chambers. Fig. 2, is a sectional elevation of our annealing wheel. Fig. 3, presents views of one of our' projecting bar-arms, with asbes- .t-us bands on it.

Fig. 4, is a side elevation of frame 2''. V In the figures a is the rim of the annealing wheel held to a central hub, which hub is fast to the upright shaft b by radiatingspokearms a. This rim may be circular or with as many sides as there are sets of bar-arms c; which arms are made in any convenient nu mber, as illustrated; and they support as beds the sheets of glass, &c. These sets support as beds the sheets of glass, as indicated by the lines representing the glass over the bars in Fig. 1; there being spaces between the bars, and between the sets or beds of bars. These bar-arms may be duplicated one over the other as in Fig. 4; and are preferably made of steel bars; though represented to be of gas pipe.

The annealing wheel laps over the flattening wheel; the two chamber walls meeting as in Fig. 1, and a cast iron beam supporting the arches overthe lapped portion; an adjustcoolest' place g of the flattening wheel stones, in the best relation to the reception position g of the sets of bar-arms c to that stone position and makingeasy thetransfer of the sheets of glass from the flattening wheel to the anas by its arrow. The flattening wheel revolves in the opposite direction, as by its arrow. The annealing wheel has a flat arch f overit; with a hanging brick or metal wall) coming down in close proximity to the sheets division wall ft. The adjustment of these walls is indicated in Fig. 1, by dotted lines; and make in the annealing chamber three anare, first a hot space, for three of the sheets on the annealing wheelfollowed by two sheets between the right hand endof the wall 1 and the wall f and two sheets in the'third and coolest space of the annealing. wheel; when the exit t' isreached and the glass taken out perfectly annealed. At'the exit i is a frame 71' frame, after the sheets of glass are drawn out of the annealing chamber on it, is turned downward bringing the sheets nearly on their edges, which bothaids their removal, and stacking for the glass cutters, and saves breakage. V

In Figs. 3, the 'bar 0 has the gaskets c" on it at intervals. This is to protect the smooth surface of the sheets from abrasion. The

usual parts and their uses, such as the fiat tening of the cylinders on the stones when at g, the push hole m, thefire grates n, the tread Wheelj, crank it, and like parts need no description. Everything else is believed to be apparent.

We claima 1. In the described mechanism for annealing glass, comprising a horizontal annealing wheel in its annealing chamber, fast to an upright shaft, and with horizontal spoke arms, projecting radially outward from itshub; a head-bar rim, fixed on the outward end of the spokes, the head bar rim having attached to it, bars, which outside of the rim, radiate of glass on the sets of bar-arms c; and a rear nealing spaces of diverse temperature; which" hinged to a rod in the exit opening; whichment made for the purpose of bringing the nealing wheel. The annealing wheel revolves horizontally outward, and make annealing beds, suited in size, to the sheets of glass, to beannealed, as set forth.

2. The described glass annealing mechanism, comprising a horizontal annealing wheel, in its annealing chamber, made with horizontal, radiating spoke arms to whose outer ends are secured head-bar rims, and to which rims are attached bars, which radiate horizontally outward, and constitute the annealing bed for the glass; there being two or more sets of beds of bars, one above the other, constructed of bars, in the manner described and set forth.

' 3. The described glass annealing mechanism, comprising an annealing, and a flattening wheel each in its chamber; the annealing wheel, with a portion of its circumferential surface, made of beds of bars, on which the glass is annealed, extending and revolving over a portion of the circumferential upper surface of the flattening wheel; the chambers of the wheels being adapted to each other; and provided with an opening between the chambers; whereby the annealing wheel is brought nearer to the source of heat, and receives readily the heat of the flattening chamber as set forth.

4. In the described glass annealing mechanism, comprisinga horizontal annealing wheel, in its annealing chamber, an exit opening 1'- in the side walls of the annealing chamber, at the place for the removal of the sheets of glass from the annealing wheel, out of the annealing chamber; in combination with the hinged and downward turning removal frame 7; whereby the sheets of glass, are readily removed to the frame, and while on the frames are turned on their edges, as set forth.

5. In the described glass annealingmechanism, comprisinga horizontal annealing wheel, constructed with radial bar beds; fast to a head-bar rim of the said wheel; the asbestus bands 0, placed at intervals on the radial bars of the annealing wheel, as set forth.

6. The'described glassannealing mechanism comprising a horizontal annealing wheel in its annealing chamber, composed of radiating spoke arms a, attached to the hub of the wheel, on the upright shaft b; and the glass beds, made of bars 0 attached to the rim (1. and projecting radially outward from the rim, and constituting the periphery of the wheel; said beds of bars constructed as described of bed sections, which sections are suited to the sheets of glass, as set forth.
